How long is a piece of string? It could last 2mins to 20 years just depends but usually if a company warrants their product for 7 years they at least expect it to last that long so you basically answered your own question.

Open it once a year to check the caps for bulge and leakage and to remove any thermal blankets (dust, usually) and you should be good to go.

Oh yeah, give the fan a good cleaning too and if it makes any noises replace.

We had a discussion on another forum about this the other day, and the general consent is that you should really use a PSU that you pull no more than 50% from. This way the components remain cool, and ageing is prolonged. PSUs are all most efficient below 50%.

I know a warranty says that a component should perfom as specified for the length of the warranty but what is the normal expected life of a PSU from Corsair, just thought I'd ask.

It's near impossible to say a product will outlive it's warranty period as everyone's usage of the product can vary greatly. The unit comes with a long warranty, and is designed to outlive it. However, should the unit fail before the warranty period expires, we will take care of you and replace the unit through our RMA processes and policies.

I strongly advise against opening the unit as this is grounds to void the warranty. Usually a can of compressed air should do the trick to clean the unit out.

mine is going to last 20-30 years:
i ve never used it.
I bought this corsair psu and a 1200psu for another pc times ago.

i placed this triple monitor setup an a table, turned on to install windows and drivers.I spent a night to oc the system to the limit and never used it again.
